This question is obviously intended for those that live in places where tap water is “safe to drink.”
I live in Southern California, where I’m at the end of a long chain of cities. Occasionally, the tap smells of sulfur, hardness changes, or it tastes… odd. I’m curious about the perspective of people that are directly involved and their reasoning.
Same. I can take tap water fine but my wife hates it. But even so, we both can tell by taste when the filter is toast. We can also tell from the way our bathroom counters get white buildup just by incidental water droplets during handwashing that we have excessively hard water. Not dangerous but not pleasant.
